Thorax, including the pleura and scutellum honey-yellow, shin- 
ing and covered with quite thick yellow pile, humeri promi- 
nent and lighter than the disc of the thorax, behind the shoulder

in the middle of the first, a triangle at the base of the second and 
third, a square occupying the middle half of the fifth and all

Legs yellow with yellow pile, tips of the tarsi dark brown, claws 
black. Wings hyaline, veins yellow, squamae white margined

One specimen, Tucson, Arizona, March 16, 1916 (J. F. Tuck- 
er). Type in the author’s collection. It agrees somewhat with 
O.micans Erichson, but its yellow not ‘‘fuscous” color, the blue- 
black abdominal markings and larger size separate it from that 
species.
